Send GIS feature events

If any point, polyline, or polygon features are selected then a OpenSpirit GIS event An OpenSpirit event that contains point, polyline, or polygon features. A receiving application will display the received features. may be sent.

From the map view, if there are such features selected you may send a GIS event An OpenSpirit event that contains point, polyline, or polygon features. A receiving application will display the received features. by clicking on this button.

This will send a GIS event An OpenSpirit event that contains point, polyline, or polygon features. A receiving application will display the received features. containing the geometry, fields, and basic display properties from all selected features. The basic display properties carried in the OpenSpirit GIS event An OpenSpirit event that contains point, polyline, or polygon features. A receiving application will display the received features. includes:

• point size and color
• line width and color
• fill color and opacity

Alternatively , if you just wish to send selected features from a single layer you may send a GIS event An OpenSpirit event that contains point, polyline, or polygon features. A receiving application will display the received features. from the selected features dialog (see: See selected feature attributes and related data )

The features will either be sent in their feature class CRS A Coordinate Reference System (the default)  or transformed to the map display CRS A Coordinate Reference System.  This choice is made in the OpenSpirit options dialog:

This options dialog is displayed by using this toolbar button:

If any feature classes are sent in a CRS A Coordinate Reference System with a datum other than WGS84 the OpenSpirit ArcGIS Extension will tag the feature class CRS A Coordinate Reference System with a preferred transform to WGS84.  The data is NOT transformed to WGS84 but this transform is included in the OpenSpirit event A message sent between OpenSpirit enabled applications. Events may be shared between applications running on different computers and operating systems. for the convenience of receiving applications that have asked OpenSpirit to deliver the spatial event A message sent between OpenSpirit enabled applications. Events may be shared between applications running on different computers and operating systems. in its project CRS A Coordinate Reference System (which may have a different datum).  The OpenSpirit ArcGIS Extension will attempt to get the preferred transform by reading the transforms defined in the ArcMap project (as defined earlier by the user of the project). If no appropriate transform is found the user is prompted to select a transform from a list based on the EPSG database used by the OpenSpirit coordinate service (the details of the EPSG parameters may be shown in order to help guide this selection)  :

  Any selected transforms are then added to the ArcMap project so the user does not need to repeat the same choice again.

 It is not necessary for the receiving application to be running on the same PC as ArcGIS. It could be running on another PC or on a Linux workstation. It must, however, be run under the same account as the ArcGIS user (or an account registered as an OpenSpirit  secondary desktop for the ArcGIS user).  The receiving application must also be enabled for listening for GIS events An OpenSpirit event that contains point, polyline, or polygon features. A receiving application will display the received features..
